CLEAR signal device specification method:
1) Write the CLEAR signal output (Y) device number in the "CLEAR signal device specification" register with
a hexadecimal number (expressed in octal numbers).
e.g. setting H0010 means Y010. When setting H0008, an operation error occurs because Y008 does not
exist.
2) Turn on the "CLEAR signal output function enable" relay and "CLEAR signal device specification function
enable" relay to specify the CLEAR signal device.
3) Execute the DSZR instruction (zero return instruction with DOG search function) or ZRN instruction (zero
return instruction).
Example program:
The following figure shows a program that can specify Y010 as the CLEAR signal output device for Y000
(pulse output destination device):

Change in Logic of Near-Point (DOG) Signal (DSZR Instruction)

Turn on or off the "DOG signal logic reverse" relay to specify the logic of the near-point (DOG) signal of the
DSZR instruction (zero return instruction with DOG search function). Use the operand (
instruction to specify the near-point (DOG) signal.

4.3.6

Change in Logic of Zero-Phase Signal (DSZR Instruction)

Turn on or off the Zero-point signal logic reverse" relay to specify the logic of the zero-phase signal of the
DSZR instruction (zero return instruction with dog search function). Use the operand (
to specify the zero-phase signal.
